This has probably been asked before, I just forget. Picked up a bunch of small primered .45acp brass at the range today, too many to just ignore and leave[128!]. Now, can these be loaded with the same charges I'm using now? Currently the two loads are:
200gr XTP's and 4.1gr Clays
230gr LRN and 3.8 Clays
And sometimes 230gr fmj and 5.6gr Universal
I know, three loads, opps.

Yep, the primers won't make any difference AFAIK. I have loaded them with the same data as my LP ones and noticed no difference.

I was wondering the same thing as I bought some CCI Blazer Brass loads after shooting deprimed them and found out they are small pistol primers.

Well, I'm going with T LEE here; I think I take what he says is true. But, I'm still listening shooters. I do like opinions.

It works the same for me. I have picked up almost 400 that others do not want to mess with.

Are the small primer loads reliable in cold weather? I read somewhere about experiments with small primers in some cartridges causing hang-fires.

I have made extensive tests with the .45 ACP revolver and found the LP primer will move bullets out before good ignition.
The SP brass cut groups by 2/3's and was even better in the 1911. Do some testing and you might like the SP brass.

The same holds true with the .44 mag and .45 Colt, LP mag primers are not as good as standard primers. Even Federal is loading mag loads with the 150 primer.
I do not go to the LP mag until the .475 and up.

Powder ignites in milliseconds, how can one determine that the bullet moves out before ignition? To violent of ignition for the case capacity effectively speeds up the burn rate and can cause poor groups

I have shot some nice groups with large pistol primers in the 45 ACP

Not sure what you mean by "good". According to my chronograph, mag primers greatly reduce the Extreme Spread when using H110, W296, Enforcer and LilGun in 44 mag. I take the lower ES to mean that ignition and combustion are more consistent.

+1, me too

I can list 100 things as to why ES and SD is bad in a revolver.
I have been testing the primers in the .44 since the early 70's and used standard primers with 296 for IHMSA, won Ohio state with 79 out of 80. All of my hunting has been with standard primers. Any weather. The chrono never gets used for working loads, it is useless.
These are average groups with my old SBH that is close to 62,000 rounds. 50 yards and I shot the can at 100. Hit the rail so I aimed higher for the last shot.

Here is a group at 200 yards while doing a drop test. Different boolit.
Then the .45 Colt Vaquero at 50 yards.

There is no way I ever did this with a mag primer.

This is one of thousands of primer tests with the .44.
This was done at -10* with a lot of wind. The standard still did better.

Here is one of many tests with a .45 ACP revolver, LP and SP primers. I don't do this for fun. I do it for knowledge.

ES and Sd are now meaningless??? Only in WV!!!

While I am impressed with your shooting skills, I'm not so impressed with some of your statements on ES and SD. Yes, at the short ranges of handguns, velocity variations don't mean much.

You can always find certain sweet spot loadings with H110/296 that will work fine with standard primers (I have no idea what your loading specifics are since you don't post them). But magnum primers enable a wide range of loadings without the worry of a stuck bullet or flintlock-like ignition.

I believe my chronograph. It tells me plainly that ignition and combustion are much more consistent shot to shot with mag primers. I don't see "minute-of-can" accuracy being much of a challenge for the ammunition at 100yds - shooter yes, ammo no.

dla, whitworth test a lot of factory loads (handgun round) that shoot extremely well at bfr's place. Some ofthose loads use LR primers. The LR primer is has a much greater force of ignition than a magnum pistol primer and yet he ignores any and all evidence that doesn't agree with his opinion

He is wrong in so many ways

I shot and hit these 2 12 guage shotgun hulls at 50 yards with Winnchester white box loads purchase at Wal Mart.





I did that with the iron sights, you either use an Ultra Dot or a scope

I have and I will continue to use Mag pistol primers with H-110/296 despite you rants

I have to ask where my pictures went, none came up.

I need to try pictures again.
Nope, photobucket changed something.

You have no idea what primers are use. Most large calibers like the .475 use LP mag primers and they are needed.
Some .500 S&W brass was cut for a LP mag primer and others cut for a LR primer. Did you know guns have been blown up when LR primers were used in LP brass because a proud primer can fire against the frame.
But you said it right---FORCE! Force not needed, heat is needed.
You have not proven a single time what you say.

Oooook then; I'm good to go loading the small primed .45acp cases later on. Whew!

Yes I do have an idea of what primer Grizzlt ammo use. How You ask? Grizzly Ammo used my 500JRH to test all of their factory loads in 500 JRH, I asked if he indeed uesed LR primers in certain loads and was told yes

It is you that has no idea and that is for sure and for certain

Several powder and gun makers told me NOT to use LR primers. I will stay with those findings and my own.
I got the virus out of my computer so here is the picture of .45 ACP revolver groups.

I see some pictures did come up. I had some program that shut down one thing at a time and wanted me to buy something. It told me I had 52 viruses when I had none. Took a lot of hunting by a friend to find it and do away with it. It was called defender and looked like Microsoft stuff. It might have been Microsoft with a time code to spend money. One thing after another stopped until nothing could be opened without a window saying to download and pay.

Not to choose sides here..i had a similar discussion with BFR last year. So being the stubborn hard headed person that i am i set out to prove him wrong. I started an all out primer testing fiasco of my own. I bought every brand primer i could find, even some old remington from the 60's a friend of mine still had. I tried, unique, bulleye, Imr4227, 2400, 296, new brass, once fired, and "darn near worn out brass" Hell I had a Western Sizzlin buffet of 44 mag garb loaded up. in all reality i got tighter groups(not much) with well used brass and LP primers than I did with any other brass/powder/primer combination. My final load ended up being 2400/federal #150/well used starline brass/ 240 keith bullet/ Ruger redhawk 7.5 1981 model. All of my testing was this summer so i have no temperature comparisons. most days testing were 95*+ and all was done between 25-50yds outside off of sandbag/ shoot n clean. Further testing to come in cold weather. Dont know if it means anything or not but he was partially correct about the issues we argued then. I feel overall that my abilities as a shooter were more important than all the other crap combined and in the long run any of the loads would have been more than accurate enough to down a white tail. My S&W 500 uses only LR primers and you can bet it'll never see an LP primer in it i can tell you that. Nor will any of my rifles ever see LP primers. I have never loaded 45 acp with SP primers and doubt i ever will. I doubt any auto in 45 acp would ever know the difference. If it does i wont be there to see it. Some of my best groups with my Colt pre series 70 National Match was with white box wal-mart ammo. I have a series 70 LW commander that nothing will shoot good in. I guess i never intended to be as accurate with my 1911's as i am with my big bore revolvers.

I like that, that you tested. That is important and what I ask. I get out of sorts when all manuals say you NEED mag primers.
The 1911 can use both the LP and SP primers because it is not a revolver. Yet there might be a tiny accuracy advantage with the SP primer and evidence is the amount of cases found cut for the SP primer.
I don't like to argue at any time. I present my findings for everyone to try, nothing is cut in stone. Just think out of the box to see if it works for you.
Many dispute and that is fine but you have to test first. Others dispute to keep an argument going forever without ever knowing a thing about it. Do the work, see what works, it might be different then what I found and I will agree with you.
It is the sharing of experience that just might help someone that is important and personal stuff needs to be left out.
None of us shoots the same stuff so results change.
Now the .500 S&W CAN use a LR primer as the case is large. My caution is to make sure your brass was not cut for a LP primer because there is brass out there. THAT IS DANGEROUS if you use a LR primer. Measure pocket depth if you pick up brass. You can cut the pocket deeper with a tool. Your safety in my concern.

I use the same loads for sp and lp brass and the accuracy is consistent enough for my purposes
